application of mid-infrared spectroscopy for de-termination of selected sensory attributes in a range of experimentally manufactured processed cheese samples.This study also evaluates mid-infrared spectroscopy against other recently proposed techniques for pre-dicting sensory texture attributes.Processed cheeses (n =32)of varying compositions were manufactured on a pilot scale.After 2and 4wk of storage at 4°C,mid-infrared spectra (640to 4,000cm −1)were recorded and samples were scored on a scale of 0to 100for 9attributes using descriptive sensory analysis.Models were devel-oped by partial least squares regression using raw and pretreated spectra.The mouth-coating and mass-form-ing models were improved by using a reduced spectral range (930to 1,767cm −1).The remaining attributes were most successfully modeled using a combined range (930to 1,767cm −1and 2,839to 4,000cm −1).The root mean square errors of cross-validation for the models were 7.4(firmness;range 65.3),4.6(rubbery;range 41.7),7.1(creamy;range 60.9),5.1(chewy;range 43.3),5.2(mouth-coating;range 37.4),5.3(fragmentable;range 51.0),7.4(melting;range 69.3),and 3.1(mass-forming;range 23.6).These models had a good practical utility.Model accuracy ranged from approximate quantitative predic-tions to excellent predictions (range error ratio =9.6).In general,the models compared favorably with previously reported instrumental texture models and near-infrared models,although the creamy,chewy,and melting models were slightly weaker than the previously reported near-infrared models.We concluded that mid-infrared spec-troscopy could be successfully used for the nondestruc-tive and objective assessment of processed cheese sen-sory quality.Received April 12,2006.Accepted October 30,2006.1Corresponding

2004,and processed cheese is an important seg-ment of this market (Wohlfarth and Richarts,2005).The United States,the largest producer of processed cheese (where 20%of all cheese consumed is processed cheese),produced 1,092,000tonnes in 2003(Wohlfarth and Ric-harts,2005).In the same year,the 25countries of the European Union produced 655,000tonnes of processed cheese (Wohlfarth and Richarts,2005).Consumer preference for a food product is principally determined by its sensory characteristics.Accurate mon-itoring and control of sensory properties will facilitate the production of high-quality products.A number of factors determine the final quality and sensory proper-ties of processed cheese (Caric´and Kala ´b,1993).These include the processing conditions used during manufac-ture,the composition of the ingredients,and the propor-tions of those ingredients added to the blend.Sensory profiling allows various quality attributes to be identified and their intensity determined (Brown et al.,2003).Sensory attributes are traditionally assessed by descriptive sensory evaluation using trained panel-ists.However,this is a time-consuming and expensive process that may lack objectivity (Blazquez et al.,2006).Although instrumental techniques such as texture pro-file analysis (TPA )and the 3-point bend test are avail-able for determining the texture attributes of food prod-ucts,these laboratory-based techniques are time-con-suming and require the use of skilled personnel in their execution (Blazquez et al.,2006).Therefore,considerable interest exists in the development of instrumental tech-niques to enable more objective,faster,and less expen-sive assessments of cheese quality to be made,including sensory aspects (Downey et al.,2005).Such a technique would assist producers to maximize yields,increasePREDICTION OF CHEESE SENSORY TEXTURE ATTRIBUTES1123throughput and efficiency,reduce labor costs,and opti-mize product quality,consistency,and customer satisfac-tion.Critical points in the manufacturing process could be monitored to ensure that the final product would meet required specifications.Recently,Kealy (2006)examined cream cheese using TPA,one of the main instrumental techniques for tex-ture measurement,and compared the results with those of a trained taste panel.Although a reasonably strong correlation was found between the taste panel results and TPA-derived hardness and adhesiveness parame-ters,the correlation for cohesiveness was not straightfor-ward.Everard (2005)also investigated the prediction of sensory attributes of processed cheese from instrumen-tal texture attributes derived from TPA,a compression test,and a 3-point bend test.He could predict the texture attributes of firmness,rubbery,creamy,chewy,frag-mentable,and mass-forming with a good level of accu-racy (Everard,2005).Spectroscopic analysis in combination with predictive mathematical models,developed using multivariate data analysis techniques such as partial least squares (PLS )regression,have potential use in controlling and monitoring the quality of raw materials through to the final product in food processing.In particular,infrared spectroscopy has been applied as an objective and nonde-structive technique to provide a rapid and real-time anal-ysis of both composition and quality (Downey,1998;Lefier et al.,2000;Ozen and Mauer,2002;Blazquez et al.,2004).Blazquez et al.(2006)modeled the sensory attributes of processed cheese using near-infrared re-flectance spectroscopy and PLS regression.They found that it was possible to model a number of attributes including firmness,melting,rubbery,and creamy.Two other studies have investigated the prediction of sensory attributes in natural cheese.Downey et al.(2005)and Sørensen and Jepsen (1998)successfully demonstrated that near-infrared spectroscopy in conjunction with PLS regression can be used to predict several sensory attri-butes of Cheddar and Danbo cheeses,respectively.Mid-infrared spectroscopy has been most widely used for de-termination of the fat and protein contents of cheese (Chen and Irudayaraj,1998).Irudayaraj et al.(1999)also investigated the use of mid-infrared spectroscopy to follow texture development in Cheddar cheese during ripening.They demonstrated that springiness could be successfully correlated with a number of bands in the mid-infrared spectra.Research has shown that mid-in-frared spectroscopy is a useful technique for characteriz-ing the changes in proteins during cheese ripening (Ma-zerolles et al.,2001).Pillonel et al.(2003)also found that mid-infrared spectroscopy may be successfully applied to the discrimination of Emmental cheese based on geo-graphic origin.Journal of Dairy Science Vol.90No.3,2007Table 1.Quantity of ingredients (g/kg)used in the production of experimental processed cheese samples Sample Emulsifyingnumber(s)Cheddar

data are currently available on the application of mid-infrared spectroscopy to determine the sensory attributes in processed cheese,or regarding evaluation of mid-infrared spectroscopy in comparison with other technologies in such an application.Therefore,the objec-tives of this study were to investigate the use of mid-infrared spectroscopy in predicting sensory texture attri-butes using a range of experimentally manufactured pro-cessed cheese samples and to compare the models devel-oped with those recently modeled using near-infrared spectra and instrumental texture attributes.These newly presented data allow for the critical evaluation of mid-infrared spectroscopy as a rapid,nondestructive technique for predicting the sensory texture attributes of processed cheese.MATERIALS AND METHODSProcessed Cheese SamplesThirty-two processed cheese batches were manufac-tured in a pilot plant at Moorepark Food Research Cen-tre,Cork,Ireland.The ingredients and formulations are listed in Table 1.The formulations,which were selected to provide samples with compositional ranges that ex-tended beyond those used commercially by processed cheese manufacturers,provided samples with a wide range of sensory characteristics.The ingredients were mixed for 1min in a jacketed cooker (Stephan UMM/SK5Universal cooker;Stephan u So ¨hne GmbH &Co.,Hameln,Germany).The blend was cooked at 80°C for 2min by indirect steam heating.During cooking,the blend was stirred constantly using a knife at 300rpm and a baffle mixer at 80rpm.The cooked blend was stored in food-grade plastic containers (225g capacity),FAGAN ET AL.1124Table2.Vocabulary of sensory attributes,their definitions,and mastication phases used to carry out the sensory analysis of processed cheese samplesSensoryattribute Definition

for samples1to16were fat and emulsifying salt,and the variables for samples17to32were moisture and emulsifying salt.Descriptive sensory analysis and mid-infrared spectroscopy were carried out at2and4wk postmanufacture.Sensory AnalysisA panel of10assessors(9females and1male),aged 35to55yr old,were selected and recruited in1998and 2000according to international standards(International Organization for Standardization,1993).The panel de-veloped a vocabulary of9texture terms:firmness,rub-bery,creamy,chewy,mouth-coating,fragmentable, melting,mass-forming,and greasy/oily(Table2),which they used to assess each sample.Samples were prepared for analysis in duplicate by removing them from storage and preparing two5-g cubes.These samples were left to equilibrate to room temperature(21°C).Each equili-brated sample was presented to assessors in a glass tumbler covered with a clock glass and labeled with a randomly selected3-digit code.Assessors were provided with deionized water and unsalted crackers to cleanse their palate between tastings.The assessors scored the samples for each attribute by marking on unstructured 100-mm line scales labeled at both ends with extremes of each attribute.The intensity of each of the descriptive terms was recorded using the Compusense v.4.0sensory data acquisition software(Guelph,Ontario,Canada).At each time point,the descriptive sensory analysis took Journal of Dairy Science Vol.90No.3,2007place over2d.The order of tasting was balanced to account for the order of presentation and carryover ef-fects(MacFie et al.,1989).All assessments were con-ducted in individual booths at the sensory laboratory at University College,Cork,which complies with interna-tional standards for the design of test rooms(Interna-tional Organization for Standardization,1988).Mid-Infrared SpectroscopyMid-infrared spectra were collected over the range of 4,000to640cm−1,with a resolution of8cm−1,using an ATI Mattson Infinity Series Fourier transform spectro-photometer(ATI Mattson,Madison,WI)controlled by WinFirst software(ATI Mattson).The sample accessory used for sample presentation was an attenuated total reflectance ZnSe crystal(Graseby Specac Ltd.,Kent, UK),with an incidence angle of45°and6internal reflec-tions.Sixty-four interferograms were coadded before Fourier transformation.Prior to mid-infrared analysis, samples were removed from storage and left to equili-brate to room temperature.This was confirmed prior to analysis using a digital thermocouple(Sensor-Tech Ltd., Co.Louth,Ireland).Processed cheese samples were wiped across the attenuated total reflectance crystal to ensure even and immediate contact.Triplicate spectra were captured for each sample and replicate spectra were averaged prior to data analysis.Multivariate Data AnalysisMultivariate data analysis was carried out using The Unscrambler software(v.8.0;Camo A/S,Oslo,Norway).PREDICTION OF CHEESE SENSORY TEXTURE ATTRIBUTES1125Figure 1.Typical mid-infrared spectrum of processed cheese.Principal component analysis of the spectra was used to examine the spectral data set for any possible outliers.Models for the prediction of sensory attributes were de-veloped using PLS regression and confirmed by cross-validation.Prior to PLS regression,spectra were pre-treated using multiplicative scatter correction (MSC ),first derivative (Savitzky-Golay,2data points each side),second derivative (Savitzky-Golay,4data points each side),and each derivative plus MSC (Geladi et al.,1985).The potential of the models to predict the sensory attri-butes was evaluated using the root mean square error of cross-validation (RMSECV ),correlation coefficient (r )and the number of PLS loadings (#L ).The range error ratio (RER )was used to determine the practical utility of the models (Williams,1987).It was calculated by di-viding the range in the reference data of a given attribute by the prediction error for that attribute.The ratio of prediction error to deviation (RPD )was calculated by dividing the standard deviation of the reference data by RMSECV.RESULTS AND DISCUSSIONMid-Infrared SpectraA number of studies have assigned the main cheese constituents (fat,protein,moisture)to specific bands in the mid-infrared spectra (Chen and Irudayaraj,1998;Chen et al.,1998;Irudayaraj and Yang,2000;Mazerolles et al.,2001).The positions of these bands are indicated in a typical mid-infrared spectrum of processed cheese from this study (Figure 1).The results of principal component analysis of the spectra were investigated to determine whether any in-fluential outliers were present in the data set.An influ-ential outlier is a sample that has both a high residual and high leverage.A high residual means that the model,Journal of Dairy Science Vol.90No.3,2007Table 3.Statistical summary of sensory attributes (n =64)Sensory attribute Mean Range SD Firmness 37.6 5.6–70.921.9Rubbery 23.3 2.9–44.614.4Creamy

fits the other samples quite well,poorly describes the sample.Leverage measures the dis-tance from the projected sample to the center or mean point.If a sample has a high leverage,it is exerting a stronger influence on the model than the remaining samples.According to these criteria,no outlier was found.Previous research has recommended that prior to analysis,a portion of the mid-infrared spectra (1,800to 2,700cm −1)might be omitted because of its low signal-to-noise ratio (Pillonel et al.,2003).This approach was used in this study,with the region 1,775to 2,830cm −1having a low signal-to-noise ratio,and was therefore omitted from analysis.In a preliminary investigation of the spectra,the region 640to 923cm −1was found to be of limited use in predicting sensory attributes and was also omitted.Therefore,only spectral data in the ranges of 930to 1,767cm −1and 2,839to 4,000cm −1were used for the multivariate data analysis.Predication of Sensory Texture Attributes by Mid-infrared SpectroscopyA summary of the values scored by the taste panel for each of the 9sensory attributes is shown in Table 3.The table highlights the high degree of variability in the data,which should support the development of robust models.Models were developed using 1)the combined spectral ranges of 930to 1,767cm −1and 2,839to 4,000cm −1,and 2)930to 1,767cm −1.The spectra were used in a number of forms:raw,MSC,first derivative,second derivative,and MSC plus each derivative step,giving 12models for each sensory attribute.A second derivative step offered no improvement in model accuracy for any attribute;hence,those prediction results are not shown.The RMSECV,r,and #L values obtained from the models developed are given in Table 4for the combined spectral range or the 930to 1,767cm −1range.These parameters allow for assessment of model strength.The preferred predictive model for an attribute (highlighted in bold in Table 4)was that which produced the lowest RMSECVFAGAN

highest r values.It was also desirable for the pre-ferred model to incorporate the lowest#L possible. The results showed that only2of the models(mouth-coating and mass-forming)were improved when the re-duced spectral range(930to1,767cm−1)was used.None of the preferred models was developed using raw spectral data(i.e.,accuracy was improved by the application of a pretreatment).Thefirmness and fragmentable attri-butes were most successfully modeled using MSC spec-tra.The application of afirst derivative step resulted in the preferred models of rubbery,creamy,mass-forming, and greasy/oily.The most accurate models for the chewy, melting,and mouth-coating attributes were achieved when the spectra were subjected to scatter correction and afirst derivative.In conjunction with the RMSECV,r,and#L,the prac-tical utility of the models can also be assessed using the RER.Models with RER of less than3have little practical utility;RER values of between3and10indicate limited to good practical utility;and values above10show that the model has a high utility value(Williams,1987).The preferred models for predicting thefirmness,rubbery, creamy,chewy,mouth-coating,fragmentable,melting, and mass-forming attributes(shown in bold in Table4) had RMSECV values of between3.1and7.4and resulted in corresponding RER values of between7.2and9.6, indicating that the models had good practical utility. Therefore,these attributes had the potential to be pre-dicted by mid-infrared spectroscopy and multivariate data analysis.The greasy/oily attribute was not success-fully modeled(RER=4.8),possibly because of the small range displayed by the samples analyzed,and will there-fore not be discussed further.A graphical display of the preferred regression model for each attribute(high-lighted in bold in Table4)is shown in Figure2A to2H. Figure2shows that there is minimal scatter in the plots, as indicated by the high r values(0.83to0.96),and that the regression lines also have slopes close to1(0.77to 0.96)and low intercepts(1.0to5.9),demonstrating a Journal of Dairy Science Vol.90No.3,2007goodfit(Figure2).The accuracy of each model can be evaluated using the coefficients of determination(R2) between the predicted and measured values,as stated by Williams(2003).The models for mass-forming and mouth-coating both provided approximate quantitative predictions because their R2lay in the range of0.66to 0.81.Good predictions were achieved for the attributes firmness,rubbery,creamy,and chewy,with R2values of between0.82and0.90.The fragmentable model was considered to be excellent,having an R2greater than 0.91.The#L must also be taken into account.This ranged from5to11for the selected models.The models forfirmness,fragmentable,mouth-coating,and mass-forming incorporated a relatively high number of load-ings(9to11),which may have implications for their robustness,because the lower#L,the more robust the model.Thefirst3loadings of the models,which accounted for greater than90%of the variation in the spectral data,are plotted in Figure3A to3H.Although a number of preferred models were developed using spectra pre-treated with afirst derivative step,interpretation of the loadings associated with these models was difficult.This was because the observed peaks and valleys did not follow the raw spectral pattern.However,second deriva-tive steps were very helpful in spectral interpretation because in this form,band intensity and peak location were maintained with those in the raw spectral pattern. Therefore,although the second derivative step did not improve any of the prediction models,the loadings pre-sented for rubbery,creamy,and mass-forming were ob-tained using second derivative spectra and those for chewy,mouth-coating,and melting were obtained using MSC second derivative spectra.The loading plots pre-sented forfirmness and fragmentable were obtained us-ing MSC spectra.Figure3A to3H shows the relation-ships among the loadings used in the prediction model and the different wavenumbers.If a wavenumber had a large positive or negative loading,this meant that thePREDICTION OF CHEESE

the predicted attribute and provided an aid to interpreting the molecular basis for predicting an attribute.The important loadings were distributed across the full spectral range used in predicting each attribute (Fig-ure 3).There was considerable structure present in all of the loading plots.In comparing the plots produced using similar spectral treatments,that is,MSC (Figure 3A and 3F),second derivative (Figure 3B and 3C),and MSC plus second derivative (Figure 3D and 3G),it was apparent that differences existed in the relative impor-tance of various regions of the spectra in predicting the different sensory attributes.For example,the region around 3,200to 3,900cm −1was shown to be of greater importance in predicting the attributes of firmness (Fig-ure 3A),chewy (Figure 3D),and melting (Figure 3G)than for the other attributes.This region of the spectra corresponded with a broad moisture absorption peak.The loadings incorporated into the firmness model ex-plained the variation across almost the full spectral range used (Figure 3A).Peaks and valleys occurred at around 1,095,1,160,and 1,269to 1,396cm −1,associated with the vibration of C–H,C–O bonds of carbohydrates;1,739,2,846,and 2,931cm −1,associated with lipids;and around 1,554,1,604,and 1,646cm −1,which are known to correspond with amides I and II.The amide I and amide II regions of the spectra were also important in predicting chewy,with peaks observed in the loading plot in the region of 1,504,1,547,1,639,and 1,655cm −1(Figure 3D).The loadings for the chewy model were also found to explain variation in the moisture absorp-tion region (3,359to 3,907cm −1),the peaks associated with lipids (1,739and 2,927cm −1),and the region around 1,080cm −1.The most important regions of the spectra for predicting mouth-coating were the regions associated with the vibration of C–H,C–O bonds of carbohydrates (987,1,072to 1,095,1,176,and 1,334to 1,427cm −1)and lipids (1,732,1,739,and 1,751cm −1;Figure 3E).Peaks were also observed in the amide I and II region (1,542,1,562,and 1,655cm −1).A number of major peaks were clearly identified in the fragmentable loading plot (Fig-ure 3F).These were 1,110,1,169,1,242,and 1,462cm −1,and 1,743,2,854,and 2,924cm −1,which corres-ponded with the vibration of the C–H,C–O bonds of carbohydrates and lipids,respectively.Emulsifying salts chelate calcium,which plays an important role in the 2-dimensional structure of processed cheese.They also aid in the dispersion of proteins,which contributes to the emulsification of fat.In this study,the emulsifying salt used was disodium phosphate.The effect of increasing the phosphate concentration was 2-fold,namely,an in-creasing ability to chelate calcium and an incremental Journal of Dairy Science Vol.90No.3,2007increase in the pH of cheese.The interaction between these 2effects (emulsifying salt and pH)will result in increased firmness of the cheese.However,this result is also dependent on the moisture content because mois-ture acts as a plasticizer in processed cheese and de-creases the concentration of the dispersed phase,hence decreasing the firmness of the processed cheese.Greater firmness is also attributed to a higher concentration of protein,and increases in the fat and water contents weaken the protein structure,thereby decreasing the firmness of the processed cheese.This explains the im-portance of the fingerprint (991to 1,400cm −1),lipid,amide,and moisture-absorption regions in predicting the firmness,chewy,fragmentable,and mass-forming attributes.The regions of the spectra that were most important in predicting the attributes of rubbery (Figure 3B)and creamy (Figure 3C)were all associated with lipids (1,739,1,743,2,846,2,858,2,916,2,919cm −1).Minor peaks were also observed in the 1,079to 1,173,1,542,and 3,556to 3,907cm −1spectral regions,which are associated with the vibration of the C–H,C–O bonds;amide II;and moisture absorption,respectively.These peaks were of particular importance in predicting the rubbery and creamy attributes,because fat in cheese has the effect of preventing the protein network of the cheese matrix from forming a tough,dense structure (Lawlor et al.,2001).The loadings for the melting model (Figure 3G)ex-plained variation in a number of different regions,in-cluding the amide I and II regions (1,547,1,654cm −1),lipid regions (1,751,2,927cm −1),and moisture-absorp-tion region (3367to 3907cm −1).All factors that influence either the content or distribution of fat,or the strength of the protein network are known to influence cheese meltability (Lefevere et al.,2000).This accounts for the significance of the moisture,amide,and lipid regions of the spectra in predicting melting.The regions of the spectra that were the most im-portant in predicting mass-forming were found to be 1,092and 1,130cm −1(C–H,C–O bond vibrations);1,535,1,547,1,646,and 1,647cm −1(amides I and II);and 1,736,1,743,and 1,751cm −1(lipids;Figure 3H).This indicates the role that the fat content and protein structure has in determining the mass-forming potential of pro-cessed cheese.These results highlight the importance of different regions across the entire spectral range used in pre-dicting the sensory textural attributes of processed cheese.The importance of different spectral regions in predicting sensory attributes is related to the effects of the formulation and composition on processed cheese texture.Changes in the formulation and composition of。

综合理论课程教育研究学法教法研究 277计部门要加强对被审计单位或部门的监督,也可考虑和高校联合起来,共同开展回头看,等等。
通过采取一系列务实、创新的举措,真正将整改工作落到实处。
2.提高质量。
无论是审计工作方式还是撰写审计报告,都要精益求精,经得住推敲。
如果不认真对待审计内容,工作拖拖拉拉、质量不高的话,那么审计出来的结果也是经不起推敲,不能加以运用的。
这样浪费了大量的人力、物力、财力资源,却没有收到实效。
所以,要全方面提高审计工作的质量。
一是端正审计工作的态度,要以高度负责的精神和态度来对待审计,不可马马虎虎地工作。
二是优化审计工作流程,创新审计工作方式。
工作要有逻辑性,按照要求按部就班、不折不扣地做好工作,做到流程清楚,逐项落实;要改变传统的工作方式,按照审计的要求创新工作思路和工作方法,力求将各项工作做得扎实、务实。
三是要撰写高质量的审计工作报告。
审计工作报告是对本次审计工作的总结,具有很强的针对性和指导性,审计工作报告质量的好坏,直接影响了本次审计是否取得成功,这对审计人员提出了更高的要求。
一方面审计人员要懂业务,会正确使用审计术语,了解并掌握审计工作的整个流程,另一方面要有较强的综合分析能力和文字综合能力,能够透过现象看本质,将审计内容进行高度概括和凝练,从而提升审计报告的质量。
3.加强运用。
要将审计后的结果加以应用,防止出现“只审不用”的现象。
被审计单位班子成员要正确认识审计出的问题,对这些问题高度重视,进行积极的整改。
另外,审计者也要加强对审计结果的运用,尤其在审计工作流程结束后,仍然要重视审计结果的运用,还要将运用情况上报给审计部门,这也是对本次审计工作的重视及肯定。
三、结语高校领导干部的经济责任审计对高校经济活动的正常开展具有非常重要的作用。
随着高校的发展,一些新情况新问题也会出现,对经济责任审计将会提出新的更高的要求。
高校领导干部的经济责任审计要紧密结合工作实际,工作者要牢固树立创新意识,不断对审计工作方式进行创新,优化工作流程,提升工作质量,切实取得经济责任审计工作的实效。

Two important examples are the Gibbs sampler and the Metropolis algorithm.In addition, several strategies are available for constructing hybrid algorithms. This paper outlines some of the basic methods and strategies and discusses some related theoretical and practical issues. On the theoretical side, results from the theory of general state space Markov chains can be used to obtain convergence rates, laws of large numbers and central limit theorems for estimates obtained from Markov chain methods. These theoretical results can be used to guide the construction of more efficient algorithms. For the practical use of Markov chain methods, standard simulation methodology provides several Variance reduction techniques and also gives guidance on the choice of sample size and allocation.SCI高被引摘要引言部分案例回顾研究背景presentAuthor(s): L YNCH, M; MILLIGAN, BG SC I被引用661Title: ANAL YSIS OF POPULATION GENETIC-STRUCTURE WITH RAPD MARKERS Source: MOLECULAR ECOLOGY, 3 (2): 91-99 APR 1994《分子生态学》英国Abstract: Recent advances in the application of the polymerase chain reaction make it possible to score individuals at a large number of loci. The RAPD (random amplified polymorphic DNA) method is one such technique that has attracted widespread interest.The analysis of population structure with RAPD data is hampered by the lack of complete genotypic information resulting from dominance, since this enhances the sampling variance associated with single loci as well as induces bias in parameter estimation. We present estimators for several population-genetic parameters (gene and genotype frequencies, within- and between-population heterozygosities, degree of inbreeding and population subdivision, and degree of individual relatedness) along with expressions for their sampling variances. Although completely unbiased estimators do not appear to be possible with RAPDs, several steps are suggested that will insure that the bias in parameter estimates is negligible. To achieve the same degree of statistical power, on the order of 2 to 10 times more individuals need to be sampled per locus when dominant markers are relied upon, as compared to codominant (RFLP, isozyme) markers. Moreover, to avoid bias in parameter estimation, the marker alleles for most of these loci should be in relatively low frequency. Due to the need for pruning loci with low-frequency null alleles, more loci also need to be sampled with RAPDs than with more conventional markers, and sole problems of bias cannot be completely eliminated.SCI高被引摘要引言部分案例词汇describe•Author(s): CLONINGER, CR; SVRAKIC, DM; PRZYBECK, TR•Title: A PSYCHOBIOLOGICAL MODEL OF TEMPERAMENT AND CHARACTER•Source: ARCHIVES OF GENERAL PSYCHIATRY, 50 (12): 975-990 DEC 1993《普通精神病学纪要》美国•引言部分回顾研究背景,常用词汇describe 被引用926•Abstract: In this study, we describe a psychobiological model of the structure and development of personality that accounts for dimensions of both temperament and character. Previous research has confirmed four dimensions of temperament: novelty seeking, harm avoidance, reward dependence, and persistence, which are independently heritable, manifest early in life, and involve preconceptual biases in perceptual memory and habit formation. For the first time, we describe three dimensions of character that mature in adulthood and influence personal and social effectiveness by insight learning about self-concepts.Self-concepts vary according to the extent to which a person identifies the self as (1) an autonomous individual, (2) an integral part of humanity, and (3) an integral part of the universe as a whole. Each aspect of self-concept corresponds to one of three character dimensions called self-directedness, cooperativeness, and self-transcendence, respectively. We also describe the conceptual background and development of a self-report measure of these dimensions, the Temperament and Character Inventory. Data on 300 individuals from the general population support the reliability and structure of these seven personality dimensions. We discuss the implications for studies of information processing, inheritance, development, diagnosis, and treatment.摘要引言部分案例•(2)说明写作目的,常用词汇有purpose, attempt, aimSCI高被引摘要引言部分案例attempt说明写作目的•Author(s): Donoho, DL; Johnstone, IM•Title: Adapting to unknown smoothness via wavelet shrinkage•Source: JOURNAL OF THE AMERICAN STATISTICAL ASSOCIATION, 90 (432): 1200-1224 DEC 1995 《美国统计学会志》被引用429次•Abstract: We attempt to recover a function of unknown smoothness from noisy sampled data. We introduce a procedure, SureShrink, that suppresses noise by thresholding the empirical wavelet coefficients. The thresholding is adaptive: A threshold level is assigned to each dyadic resolution level by the principle of minimizing the Stein unbiased estimate of risk (Sure) for threshold estimates. The computational effort of the overall procedure is order N.log(N) as a function of the sample size N. SureShrink is smoothness adaptive: If the unknown function contains jumps, then the reconstruction (essentially) does also; if the unknown function has a smooth piece, then the reconstruction is (essentially) as smooth as the mother wavelet will allow. The procedure is in a sense optimally smoothness adaptive: It is near minimax simultaneously over a whole interval of the Besov scale; the size of this interval depends on the choice of mother wavelet. We know from a previous paper by the authors that traditional smoothing methods-kernels, splines, and orthogonal series estimates-even with optimal choices of the smoothing parameter, would be unable to perform in a near-minimax way over many spaces in the Besov scale.Examples of SureShrink are given. The advantages of the method are particularly evident when the underlying function has jump discontinuities on a smooth backgroundSCI高被引摘要引言部分案例To investigate说明写作目的•Author(s): OLTV AI, ZN; MILLIMAN, CL; KORSMEYER, SJ•Title: BCL-2 HETERODIMERIZES IN-VIVO WITH A CONSERVED HOMOLOG, BAX, THAT ACCELERATES PROGRAMMED CELL-DEATH•Source: CELL, 74 (4): 609-619 AUG 27 1993 被引用3233•Abstract: Bcl-2 protein is able to repress a number of apoptotic death programs. To investigate the mechanism of Bcl-2's effect, we examined whether Bcl-2 interacted with other proteins. We identified an associated 21 kd protein partner, Bax, that has extensive amino acid homology with Bcl-2, focused within highly conserved domains I and II. Bax is encoded by six exons and demonstrates a complex pattern of alternative RNA splicing that predicts a 21 kd membrane (alpha) and two forms of cytosolic protein (beta and gamma). Bax homodimerizes and forms heterodimers with Bcl-2 in vivo. Overexpressed Bax accelerates apoptotic death induced by cytokine deprivation in an IL-3-dependent cell line. Overexpressed Bax also counters the death repressor activity of Bcl-2. These data suggest a model in which the ratio of Bcl-2 to Bax determines survival or death following an apoptotic stimulus.SCI高被引摘要引言部分案例purposes说明写作目的•Author(s): ROGERS, FJ; IGLESIAS, CA•Title: RADIATIVE ATOMIC ROSSELAND MEAN OPACITY TABLES•Source: ASTROPHYSICAL JOURNAL SUPPLEMENT SERIES, 79 (2): 507-568 APR 1992 《天体物理学杂志增刊》美国SCI被引用512•Abstract: For more than two decades the astrophysics community has depended on opacity tables produced at Los Alamos. In the present work we offer new radiative Rosseland mean opacity tables calculated with the OPAL code developed independently at LLNL. We give extensive results for the recent Anders-Grevesse mixture which allow accurate interpolation in temperature, density, hydrogen mass fraction, as well as metal mass fraction. The tables are organized differently from previous work. Instead of rows and columns of constant temperature and density, we use temperature and follow tracks of constant R, where R = density/(temperature)3. The range of R and temperature are such as to cover typical stellar conditions from the interior through the envelope and the hotter atmospheres. Cool atmospheres are not considered since photoabsorption by molecules is neglected. Only radiative processes are taken into account so that electron conduction is not included. For comparison purposes we present some opacity tables for the Ross-Aller and Cox-Tabor metal abundances. Although in many regions the OPAL opacities are similar to previous work, large differences are reported.For example, factors of 2-3 opacity enhancements are found in stellar envelop conditions.SCI高被引摘要引言部分案例aim说明写作目的•Author(s):EDV ARDSSON, B; ANDERSEN, J; GUSTAFSSON, B; LAMBERT, DL;NISSEN, PE; TOMKIN, J•Title:THE CHEMICAL EVOLUTION OF THE GALACTIC DISK .1.

The abundance analysis was made with greatly improved theoretical LTE model atmospheres. Through the inclusion of a great number of iron-peak element absorption lines the model fluxes reproduce the observed UV and visual fluxes with good accuracy. A new theoretical calibration of T(eff) as a function of Stromgren b - y for solar-type dwarfs has been established. The new models and T(eff) scale are shown to yield good agreement between photometric and spectroscopic measurements of effective temperatures and surface gravities, but the photometrically derived very high overall metallicities for the most metal rich stars are not supported by the spectroscopic analysis of weak spectral lines.•Author(s): PAYNE, MC; TETER, MP; ALLAN, DC; ARIAS, TA; JOANNOPOULOS, JD•Title:ITERA TIVE MINIMIZATION TECHNIQUES FOR ABINITIO TOTAL-ENERGY CALCULATIONS - MOLECULAR-DYNAMICS AND CONJUGA TE GRADIENTS•Source: REVIEWS OF MODERN PHYSICS, 64 (4): 1045-1097 OCT 1992 《现代物理学评论》美国American Physical Society SCI被引用2654 •Abstract: This article describes recent technical developments that have made the total-energy pseudopotential the most powerful ab initio quantum-mechanical modeling method presently available.

It demonstrates that the percentage increase in plant growth produced by raising the air's CO2 content is generally not reduced by less than optimal levels of light, water or soil nutrients, nor by high temperatures, salinity or gaseous air pollution. More often than not, in fact, the data show the relative growth-enhancing effects of atmospheric CO2 enrichment to be greatest when resource limitations and environmental stresses are most severe.SCI高被引摘要引言部分案例介绍论文的重点内容或研究范围emphasizing •Author(s): BESAG, J; GREEN, P; HIGDON, D; MENGERSEN, K•Title: BAYESIAN COMPUTATION AND STOCHASTIC-SYSTEMS•Source: STATISTICAL SCIENCE, 10 (1): 3-41 FEB 1995《统计科学》美国•SCI被引用296次•Abstract: Markov chain Monte Carlo (MCMC) methods have been used extensively in statistical physics over the last 40 years, in spatial statistics for the past 20 and in Bayesian image analysis over the last decade. In the last five years, MCMC has been introduced into significance testing, general Bayesian inference and maximum likelihood estimation. This paper presents basic methodology of MCMC, emphasizing the Bayesian paradigm, conditional probability and the intimate relationship with Markov random fields in spatial statistics.Hastings algorithms are discussed, including Gibbs, Metropolis and some other variations. Pairwise difference priors are described and are used subsequently in three Bayesian applications, in each of which there is a pronounced spatial or temporal aspect to the modeling. The examples involve logistic regression in the presence of unobserved covariates and ordinal factors; the analysis of agricultural field experiments, with adjustment for fertility gradients; and processing oflow-resolution medical images obtained by a gamma camera. Additional methodological issues arise in each of these applications and in the Appendices. The paper lays particular emphasis on the calculation of posterior probabilities and concurs with others in its view that MCMC facilitates a fundamental breakthrough in applied Bayesian modeling.SCI高被引摘要引言部分案例介绍论文的重点内容或研究范围focuses •Author(s): HUNT, KJ; SBARBARO, D; ZBIKOWSKI, R; GAWTHROP, PJ•Title: NEURAL NETWORKS FOR CONTROL-SYSTEMS - A SURVEY•Source: AUTOMA TICA, 28 (6): 1083-1112 NOV 1992《自动学》荷兰Elsevier•SCI被引用427次•Abstract:This paper focuses on the promise of artificial neural networks in the realm of modelling, identification and control of nonlinear systems.

For instance, examination of trade-offs between reproduction and survival usually rely on individually marked animals, for which the exact time of death is most often unknown, because marked individuals cannot be followed closely through time.Thus, the quantitative analysis of survival studies and experiments must be based oncapture-recapture (or resighting) models which consider, besides the parameters of primary interest, recapture or resighting rates that are nuisance parameters. 结构式摘要•T his paper synthesizes, using a common framework, these recent developments together with new ones, with an emphasis on flexibility in modeling, model selection, and the analysis of multiple data sets. The effects on survival and capture rates of time, age, and categorical variables characterizing the individuals (e.g., sex) can be considered, as well as interactions between such effects. This "analysis of variance" philosophy emphasizes the structure of the survival and capture process rather than the technical characteristics of any particular model. The flexible array of models encompassed in this synthesis uses a common notation. As a result of the great level of flexibility and relevance achieved, the focus is changed from fitting a particular model to model building and model selection.SCI摘要方法部分案例•方法部分•(1)介绍研究或试验过程,常用词汇有test,study, investigate, examine,experiment, discuss, consider, analyze, analysis等•(2)说明研究或试验方法,常用词汇有measure, estimate, calculate等•(3)介绍应用、用途,常用词汇有use, apply, application等SCI高被引摘要方法部分案例discusses介绍研究或试验过程•Author(s): LIANG, KY; ZEGER, SL; QAQISH, B•Title: MULTIV ARIATE REGRESSION-ANAL YSES FOR CATEGORICAL-DATA •Source:JOURNAL OF THE ROY AL STA TISTICAL SOCIETY SERIES B-METHODOLOGICAL, 54 (1): 3-40 1992《皇家统计学会志,B辑:统计方法论》•SCI被引用298•Abstract: It is common to observe a vector of discrete and/or continuous responses in scientific problems where the objective is to characterize the dependence of each response on explanatory variables and to account for the association between the outcomes.

The structural function of surfactants in mesophase formation can to a first approximation be related to that of classical surfactants in water or other solvents with parallel roles for organic additives. The effective surfactant ion pair packing parameter, g = V/alpha(0)l, remains a useful molecular structure-directing index to characterize the geometry of the mesophase products, and phase transitions may be viewed as a variation of g in the liquid-crystal-Like solid phase. Solvent and cosolvent structure direction can be effectively used by varying polarity, hydrophobic/hydrophilic properties and functionalizing the surfactant molecule, for example with hydroxy group or variable charge. Surfactants and synthesis conditions can be chosen and controlled to obtain predicted silica-based mesophase products. A room-temperature synthesis of the bicontinuous cubic phase, MCM-48, is presented. A low-temperature (100 degrees C) and low-pH (7-10) treatment approach that can be used to give MCM-41 with high-quality, large pores (up to 60 Angstrom), and pore volumes as large as 1.6 cm(3)/g is described.Estimates 介绍研究或试验过程SCI高被引摘要方法部分案例•Author(s): KESSLER, RC; MCGONAGLE, KA; ZHAO, SY; NELSON, CB; HUGHES, M; ESHLEMAN, S; WITTCHEN, HU; KENDLER, KS•Title:LIFETIME AND 12-MONTH PREV ALENCE OF DSM-III-R PSYCHIATRIC-DISORDERS IN THE UNITED-STA TES - RESULTS FROM THE NATIONAL-COMORBIDITY-SURVEY•Source: ARCHIVES OF GENERAL PSYCHIATRY, 51 (1): 8-19 JAN 1994•《普通精神病学纪要》美国SCI被引用4350次•Abstract: Background: This study presents estimates of lifetime and 12-month prevalence of 14 DSM-III-R psychiatric disorders from the National Comorbidity Survey, the first survey to administer a structured psychiatric interview to a national probability sample in the United States.Methods: The DSM-III-R psychiatric disorders among persons aged 15 to 54 years in the noninstitutionalized civilian population of the United States were assessed with data collected by lay interviewers using a revised version of the Composite International Diagnostic Interview. Results: Nearly 50% of respondents reported at least one lifetime disorder, and close to 30% reported at least one 12-month disorder. The most common disorders were major depressive episode, alcohol dependence, social phobia, and simple phobia. More than half of all lifetime disorders occurred in the 14% of the population who had a history of three or more comorbid disorders. These highly comorbid people also included the vast majority of people with severe disorders.Less than 40% of those with a lifetime disorder had ever received professional treatment,and less than 20% of those with a recent disorder had been in treatment during the past 12 months. Consistent with previous risk factor research, it was found that women had elevated rates of affective disorders and anxiety disorders, that men had elevated rates of substance use disorders and antisocial personality disorder, and that most disorders declined with age and with higher socioeconomic status. Conclusions: The prevalence of psychiatric disorders is greater than previously thought to be the case. Furthermore, this morbidity is more highly concentrated than previously recognized in roughly one sixth of the population who have a history of three or more comorbid disorders. This suggests that the causes and consequences of high comorbidity should be the focus of research attention. The majority of people with psychiatric disorders fail to obtain professional treatment. Even among people with a lifetime history of three or more comorbid disorders, the proportion who ever obtain specialty sector mental health treatment is less than 50%.These results argue for the importance of more outreach and more research on barriers to professional help-seekingSCI高被引摘要方法部分案例说明研究或试验方法measure•Author(s): Schlegel, DJ; Finkbeiner, DP; Davis, M•Title:Maps of dust infrared emission for use in estimation of reddening and cosmic microwave background radiation foregrounds•Source: ASTROPHYSICAL JOURNAL, 500 (2): 525-553 Part 1 JUN 20 1998 SCI 被引用2972 次《天体物理学杂志》美国•The primary use of these maps is likely to be as a new estimator of Galactic extinction. To calibrate our maps, we assume a standard reddening law and use the colors of elliptical galaxies to measure the reddening per unit flux density of 100 mu m emission. We find consistent calibration using the B-R color distribution of a sample of the 106 brightest cluster ellipticals, as well as a sample of 384 ellipticals with B-V and Mg line strength measurements. For the latter sample, we use the correlation of intrinsic B-V versus Mg, index to tighten the power of the test greatly. We demonstrate that the new maps are twice as accurate as the older Burstein-Heiles reddening estimates in regions of low and moderate reddening. The maps are expected to be significantly more accurate in regions of high reddening. These dust maps will also be useful for estimating millimeter emission that contaminates cosmic microwave background radiation experiments and for estimating soft X-ray absorption. We describe how to access our maps readily for general use.SCI高被引摘要结果部分案例application介绍应用、用途•Author(s): MALLAT, S; ZHONG, S•Title: CHARACTERIZATION OF SIGNALS FROM MULTISCALE EDGES•Source: IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE, 14 (7): 710-732 JUL 1992•SCI被引用508次《IEEE模式分析与机器智能汇刊》美国•Abstract: A multiscale Canny edge detection is equivalent to finding the local maxima ofa wavelet transform.

Fusion design tradeoffs in coherent cache hierarchies for accelerators

*
Chip designers have shown increasing interest in inte grating specialized fixed-function coprocessors into multi core designs to improve energy efficiency. Recent work in academia [11, 37] and industry [16] has sought to enable loops. The sequential program now needs to migrate across the chip utilizing the appropriate accelerator for each program region. As the execution migrates, it has become increasingly challenging to retain the temporal and spatial locality of the original program as well as manage the data sharing. We show that with the increasing energy cost of wires and caches relative to compute operations, it is imperative to op timize data movement to retain the energy benefits of accel erators. We develop FUSION, a lightweight coherent cache hierarchy for accelerators and study the tradeoffs compared to a scratchpad based architecture. We find that coherency, both between the accelerators and with the CPU, can help minimize data movement and save energy. FUSION leverages temporal coherence (32] to optimize data movement within the accelera tor tile. The accelerator tile includes small per-accelerator LO caches to minimize hit energy and a per-tile shared cache to improve localized-sharing between accelerators and minimize SION improves peiformance by 4.3 x compared to an oracle data exchanges with the host LLC.

Introduction to DevelopmentTo overcome the performance and scalability problems that CGI brings, Microsoft developed a new way for developers to build scalable applications. This high performance alternative is called the Internet Server Application Programming Interface(ISAPI). Instead of housing functionality in executable files, ISAPI uses DLLs. Using DLLs instead of executable programs has some definite performance and scalability advantages The ISAPI extension could also be called with arguments that will allow a single ISAPI extension to perform multiple tasks. Just as in the CGI example, the directory must have execute permissions enabled, or the DLL will be downloaded to the client rather than run on the server. ISAPI extensions are typically used to process client requests and output a response as HTML, which is very similar to the way CGI programs are used.ISAPI filters perform a function that can’t be directly duplicated with CGI applications. ISAPI filters are never explicitly called; instead, they are called by IIS in response to certain events in the life of a request. The developer can request that an ISAPI filter be called whenever any of the following events occur:1.When the server has preprocessed the client headers2.When the server authenticates the client3.When the server is mapping a logical URL to a physical URL4.Before raw data is sent from the client to the server5.After raw data is sent from the client to the server but before the server processes it 6.When the server logs information7.When the session is endingAs with any filter, ISAPI filters should request only the notifications it requires and process them as quickly as possible. One of the more common uses of ISAPI filters is to provide custom authentication. Another use is to modify the HTML that will be sent to the client. For example, an ISAPI filter could be used to change the background color of each page. Because ISAPI filters aren’t nearly as common as ISAPI extensions, I won’t cover them any further in this book. If you want to learn more about ISAPI extensions, you can check out my book Inside Server-Based Applications (Microsoft Press, 1999).ISAPI specifies several entry-point functions that must be exported from the DLL. Using these entry points, IIS can load the DLL; call the functions that it implements, passing in parameters as required; and receive the data to write back to the browser. ISAPI requires only two entry-point functions to be implemented these entry points, IIS can load the DLL;call the functions that it implements, passing in parameters as required; and receive the data to write back to the browser. ISAPI requires only two entry-point functions to be implementedA Better Solution: Active Server PagesIf you’re wondering why we’ve dwelt on th e alternatives to in a book about programming , the answer lies in the details of the implementation of and its predecessor, Active Server Pages (ASP). Understanding ISAPI is required for adept understanding of ASP and thus .During the beta of IIS 2.0, which became part of Windows NT 4.0, Microsoft introduced a new technology initially codenamed “Denali.” This was during Microsoft’s “Active” period and so the technology was eventually named Active Server Pages, or ASP. Several versions of have been released, most notably the versions included with Windows NT 4.0 Option Pack (ASP 2.0 and IIS 4.0) and Windows 2000 (ASP 3.0 and IIS 5.0). For the purposes of this discussion, I’ll consider ASP as a whole, without referring t o version differences became an instant hit, in large part because it made something that was difficult(create dynamic Web content) relatively easy. Creating CGI applications and ISAPI applications wasn’t terribly difficult, but using ASP was much simpler By default, ASP uses VBScript. Literally millions of developers are at least somewhat familiar with Visual Basic, Visual Basic for Applications (VBA), or VBScript. For these developers, ASP was the way to enter the Internet age. Certainly the developers could have learned a new programming language, but they didn’t have to with ASP. Partly because of its use of VBScript, ASP became a viable way to build Web applications.Just as important was the relatively easy access to databases allowed through Microsoft ActiveX Data Objects (ADO). When you need to generate dynamic content, that dynamic content obviously needs to come from somewhere, and ADO made it easy to get at that data.Finally, and perhaps most important, the development model allowed developers to essentially write code and run it. There was no need to perform compilation or elaborate installation steps. the architects were careful to capture this same development model, even though what’s going on under the covers is quite a bit different.A New Solution: When version 3.0 of was released along with Windows 2000, it became clearer that the future of software development was closely tied to the future of the Web. As part of its .NET initiative, Microsoft has introduced , a new version of ASP that retains the model of development ASP developers have come to know and love: youcan create the code and place it in the correct directory with the proper permissions, and it will just work. also introduces innovations that allow easier separation of the development of the core of an application and its presentation. adds many features to and enhances many of the capabilities in classic isn’t merely an incremental improvement to ASP; it’s really a completely new product, albeit a new product designed to allow the same development experience that ASP developers have enjoyed. Here are some of the notable features of : .NET Framework: The .NET Framework is an architecture that makes it easier to design Web and traditional applications.Common language runtime: The common language runtime provides a set of services for all languages. If you’re an ASP developer who has had to combine ASP scripting with COM objects, you’ll apprecia te the beauty of a common set of types across many languages.Compiled languages: provides enhanced performance through the use of compiled languages. Compiled languages allow the developer to verify that code is at least syntactically correct. ASP doesn’t provide any such facility, so simple syntax errors might not be caught until the first time the code is executed.Cool new languages Visual Basic: .NET is a completely new version of Visual Basic that provides a new, cleaner syntax. C# is a new language designed to look and feel a lot like C++, but without some of the unsafe features that make C++ difficult to use to create reliable applications. These two languages are available out of the box, but other languages will be available from third parties as well. As of this writing, COBOL and Eiffel implementations should be available for Visual Studio .NET as well.Visual Studio .NET: Visual Studio .NET is a cool new development environment that brings rapid application development (RAD) to the server.Improved components: The .NET Framework supports the use of new types of components that can be conveniently replaced in a running application.Web Forms: Web Forms allow Visual Basic–like development, with event handlers for common HTML widgets.XML Web services: XML Web services enable developers to create services and then make them available using industry standard protocols.: ADO for the .NET Framework is a new version of the technology that allows applications to more conveniently get at data residing in relational databases and in other formats, such as Extensible Markup Language (XML.) ConclusionThis brief history of Web development should provide you with a foundation as youcontinue reading about . Learning a programming language or development environment is much like learning a human language. Although books that cover the syntax and vocabulary are helpful, it’s often just as useful to understand the history of the people who use the language.If you’re an develope r, much of this chapter might be a review for you, but I hope that you’ve added something to your understanding of the history of . If you’re new to ASP and , understanding the history of ASP and what came before it will be useful as you begin to explore the exciting new technologies that make up .About Active Server Aside from the burden is not only (ASP) version of the next; It also provides a unified Web development models, including the development of enterprise-class Web applications generated personnel for the various services. grammar largely compatible with ASP, it also provides a new programming model and structure, flexibility and stability can produce better applications, and to provide better security protection. Through the existing ASP applications, gradually add functions to enhance ASP applications functions.When building applications, developers can use Web or XML Web services, or in any manner they deemed appropriate portfolio. Each functional access to the same support structure, so that you can use as a certification program, buffer frequently used data, or configuration of applications for self definition, only listed a few possibilities here.You can use Web-based generation of powerful the Web page. These generated pages, can be used to build public complaints server UI elements, and programming for the implementation of their common task. You can use these complaints to the building or from reusable components generated Web definition, thus simplifying the code page. For more information, please see Web pages. XML Web services provide a means of remote access server functions. Use XML Web services, enterprises can open data or business logic programming interface, and client-server applications and can acquire and operate these programming interfaces. Through the use of information such as web and XML standards such as the transmission of data across mobile firewall, XML Web services to customers - in-server or server-server programmed for data exchange. XML Web services without relying on specific components or technology transfer targets agreed. Therefore, the use of any language, using any component model, operating system and in any operating procedures can visit XML Web services. and.

Sentiment analysis determines the perspective of the author and identifies the positive, negative and neutral reviews. It provides the reviews or opinions of people‟s on text, article and product which can be positive, negative or neutral. Reviews on the different websites, social networking sites is an important source to collect the information regarding various brands of product and new features in technology (e.g. Windows, Mobiles). During the sentiment analysis various classification tools within the NLP are used to find out the positivity and negativity of reviews or comments. The paper presents a length aware hybrid approach to analyses the reviews either as positive or negative and present approach is tested on SuperFetch data set. The present approach is a combination of both supervised machine learning techniques that are Support Vector Machine and K-Nearest Neighbor in which SVM is working great for large size review and KNN is working best for small size review.Index Terms: Sentiment analysis, SVM, KNN, SuperFetch review.© 2016 Published by MECS Publisher.

IntroductionWith the rapid growth of online websites and social networking sites, everybody express their views regarding article, product on these sites [12]. The internet or web becomes a necessity in every person‟s life. On each day everybody is using online websites to express their reviews or comments, providing feedback and asking a question and other business or companies can take decision according to feedback. Sentiment analysis depicts the mood or feeling of individual about various entities and their attributes [11]. Sentiment analysis is a task to express people‟s opinions about an entity, article and product etc.In natural language processing (NLP) different machine learning approaches are utilized to determine the * Corresponding author:E-mail address: babbaljeet001@, naveencse2k4@sentiments of a huge amount of products, services, and text etc. Sentiment analysis provides many facilities to implement new applications which have a major role in business, medical, data mining and evaluate the feedback of different latest and old products.The reviews or comments of individuals in sentiment analysis can be classified into various ways like positive and negative reviews. Positive reviews have high polarity than the negative reviews. According to the reviews by various experts, one can easily find out the quality of technique. The analysis of sentiment work up with few difficulties: Among different things, it must be resolved whether document or segment thereof is subjective or objective and whether or not the sentiment communicated is positive or negative.The main steps involved in the research are Pre-processing of text, analysis of data and classification and evaluation of result. On numerous websites, people share their views in the form of …comments‟. These reviews and comments are the main elements that confirm the sentiment of people as these reviews as original. The sentiment analysis on the website is done in three steps: (a) Determine the sentiment expression. (b) Determining the polarity of reviews (positive, negative and neutral). (c) A classification approach is utilized to classify the sentiments on the website [2]. It has increased much consideration as of late and studies individual‟s emotio ns towards certain substances [1]. Sentiment analysis deal with several challenges. The description of element considered in this area. It is not a cup of tea. For example sentiments about any product can be determined by positive and negative opinions of people on the product.In the present work find out the reviews of a specialized article (e.g. SuperFetch). Determine the positive and negative survey of individuals in this article. On the basis of the reviews of the expert define how much that article technically sound or not. The positive review concerning article gives high polarity. A combined approach of Support Vector Machine and K-Nearest Neighbor is used to classify the reviews. The rest of the paper is organized as follows: Section 2 describes the some related work done in this field. Section 3 explains the proposed approach in identifying the reviews. Section 4 provides the results obtained in the proposed work along with a brief discussion. Section 5 concludes work done in this research and work to be done in the future.1.1. Applications∙Aid in decision making- Decision making is an integral part of our life. It ranges from “which technology‟s feature to use”, “which product to buy”, “which bank insurance policies to go for”, “which restaurant to go”. Sentiment An alysis (SA) can be utilized to decide and select from the available options on the basis of general opinions expressed by other users.∙Business Strategies- Many of business strategies are being guided with regard to response from the public.The various companies‟ aims to satisfy the requirements and demands of the users, so strategic moves of the companies are driven through public views and opinions. With the world connected via technology events have a global impact; issue/failure on one part of the globe has an impact on opposite corners of the world. Therefore it becomes quite necessary to drive products/services per the general public view point.∙Application as sub-component technology- The sentiment analysis has a major role in enabling technology for different systems. In some websites whenever ads are displayed in the sidebars, it‟s helpful to show ads when relevant positive sentiments are detected and nix the ads once negative sentiments are detected. The question-answering is another area where sentiment analysis may be helpful as opinion oriented question might need completely different treatment [13].∙Application to review related websites- The most common application in within the reviews of costumer products, services, and articles. There are several websites that give reviews related to the article. For example is the website that provides numerous reviews related to mobile phones, Windows, DOS, and Memory management. Summarizing opinions or reviews of the public are an important task today, so before using the latest features comes in the technology, people can aware to make decision regarding the technology means good or not for future [10].2. Related WorkThis section presents a comprehensive literature survey of research related to various sentiment analysis classification approaches. Various sentiment analysis related research papers till date have been studied and their brief is presented in this section.Mudinas et al. The paper presented a combination of both lexicon and learning based approaches for sentiment analysis. The paper mainly focused on the anatomy of pSenti- a concept level sentiment analysis and combined approach are tested on two types of data set including CNET software reviews and IMDB movie reviews. In the concept level sentiment analysis, pSenti is originated by combining both lexicon and learning based techniques. The supervised machine learning part is not simply responsible for smaller tasks such as adjusting sentiment values or finding additional sentiment words, however is really responsible for evaluating all the ingredients of sentiment process as well as semantic rules utilized to get the final output. The main advantage of hybrid approach employing a lexicon/machine learning techniques is to achieve more effective of each word- stability also as readability from a correctly designed lexicon, and also the high accuracy of the popular supervised machine learning approach. The of performance of sentiment analysis mainly depends on the sentiment of comments or reviews; if there‟s a clear separation between positive and negative value distribution, the lexicon based technique would work best, otherwise machine learning would well raise the performance. The result shows that even without subjective detection, the combined approach pSenti can achieve 82.50% accuracy that is just slightly below the bag-of-words Support Vector Machine [8].Amira Shoukry et al. The paper presented a sentiment analysis of Egyptian dialect tweets and applied sentence level analysis utilizing a hybrid approach. This approach combines each machine learning (ML) approach using Support Vector Machine (SVM) and semantic orientation (SO) techniques. This approach includes building a classifier utilizing the unigrams, bigrams and trigrams as well as new thebigrams and trigrams), Unigrams produces the best results at threshold 0. It is good to combine the all unigrams, bigrams and trigrams as features to increase the performance of sentiment analysis. The accuracy achieved by Support Vector Machine (SVM) classifier is 82.9% in case of unigrams. When comparing the results of both obtained in ML experiment and semantic orientation, the accuracy (0.806) obtained in SVM learning algorithm greater than achieved using semantic orientation technique‟s accuracy (0.719). After combining both ML and SO accuracy (A) is 0.844 and precision (P) is 0.842, recall (R) is 0.844 and f-measure is 0.842 [3]. Changliang Li et al. The paper introduced a Chinese feeling Treebank over social data because there are not very many resources introduced in sentiment analysis for Chinese and progress is kept down because of expansive, marked corpus and capable models. It identified 13550 marked sentences from movie reviews. The paper introduced a Recursive Neural Deep model (RNDM) figuring out how to sentiment label based on recursive deep learning. The paper considers the sentiment about the sentence and identifying review is positive and negative. For sentence level based sentiment, this model used baselines such as Naïve Bayes, Maximum Entropy and Support Vector Machine. The total accuracy obtained by RNDM is maximum (90.8%) compared to Naïve Bayes (78.65%), Maximum Entropy (87.46%) and Support Vector Machine (84.9%) and RNDM gets the highest performance [7].Grandi et al. In this paper observed that the present sentiment analysis technique is satisfactory for a single entity, but can produce wrong results when with the arrangement of various items. Paper is importing techniques with the help of voting theory and according to the preference aggregation to collect a set of multiple items with high accuracy. The Paper proposed notion of Borda count, which joins public‟sentiment, according to similar comparative preference information and demonstrate this class of standards fulfills various properties which a characteristics understanding in sentiment area. The SP (sentiment preference structure) is used over a set of candidates. Borda always behaves better than random procedure in identifying the winner in complete profile [6].Tan et al. The paper developed sentiment categorization on the basis of Chinese language documents with the size of 1024 documents. The feature selection methods (IG, MI, CHI, and DF) and machine learning methods (K-Nearest Neighbor, Winnow classifier, Centroid classifier, SVM and Naïve Bayes) are conducted to find out the Chinese language sentiment. The results achieved suggest that IG performance best in sentiment phrases selection and Support Vector Machine (SVM) for sentiment classification and it contains the reviews from three different areas like movie, education and house, also found that sentiment classifier mainly dependent on the topics. The dataset contains 507 documents related to education, 248 to house and 266 documents related to the movie. The Precision, Recall and F-Measure parameters are used to evaluate the performance of all the classifiers [4].Guerrero et al.The paper analyzed people‟s emotions, reviews, feelings about the product, services and organizations. Different tools and techniques are implemented for sentiment analysis. Compared some free access web services, analyze their capabilities and score to different pieces of text according to their sentiments. Machine learning and lexicon based approaches are utilized. 15 web services computed for the purpose of sentiment analysis. Some of these services belong to personal companies, however, still they allow to restricted free access to their functionalities and others are completely free services. This fact is interesting to the users who want to incorporate sentiment analysis capability among their own platforms while not having to develop their own algorithms; thus, these tools are particularly interesting for researching purposes and fast prototyping. Besides, because of the actual fact that the chosen services can work as web services, inclusion of them into any platform is basically simple. From the results produced, the services like Alchemy and Semantria might be taken into consideration for any kind of text. Sentiment analysis could also be extremely interesting to the user if the analyzed text is quite high and you would like to classify them [5].3. MethodologyThis section provides the information about the present hybrid approach and various parameters that are used to evaluate the results and also the various steps that are taken into consideration to complete the proposed work.3.1. Data setThe data set is a collection of technical article reviews (e.g. SuperFetch), which is a memory management feature find out in various Windows. The reviews of the SuperFetch have collected from the websites such as , and also from the various professionals of Universities or Colleges. These websites provide detailed information related to positive and negative reviews of different articles given by various professionals. The collected reviews are stored in an excel file, then directly fetch to the MS SQL server for further processing. All the collected reviews are divided into three parts like 50, 100 and 120 to evaluate the result.3.2. PreprocessingThe data preprocessing or cleaning step is more important in sentiment analysis. It is the process of preparing the text before the classification. The preprocessing includes the removal of extra words which are not helpful for identification of sentiments. In case of word level, different words in sentence don‟t have any impact if treated as one dimensional in the classification process [9]. Including those words in the text make the classification more tough. So, there is a process to overcome the noise level in text should help increase the performance of the classifier is called preprocessing. The main step in this process is the removal of stop words is described below. The preprocessing step mainly includes the removal of stop words. In Information Retrieval, stop words removal is a common process to get rid of words that are extremely common which don‟t add substantial value to the classification process. These common words like is, he, it, a, an, and the y‟recollectively known as stop words. Because the inclusion of these words in a review does not give any useful information, they are removed.Fig.1. Flow Chart of Removal of Stop Words3.3. Proposed ApproachThe proposed hybrid approach is a combination of supervised machine learning approaches: SVM and KNN. The present hybrid approach is utilized to classify the reviews of SuperFetch in which Support Vector Machine classifier is working well to evaluate the large size reviews and KNN is working best to evaluate the small size review. Both approaches are combined in such a way that to increase the effectiveness of the present hybrid approach.∙Support Vector MachineSupport Vector Machine is well known for their good generalization performance and has been applied to many sentiment analysis problems. Training and testing data are involved in classification task, which consists of data instances. One class label and various features are contained in each instance in the training set. In basic form, a SVM learns to find a hyper plane that separates both positive and negative examples maximum margins. The Support Vector Machine classifier is most effective classifier to increase the performance using large size sentence during the classification.∙K-Nearest NeighborIt is the classifier that relies on the labels of category and finds a k-nearest neighbor during the classification. Assign the weight to the neighbor based on their distance from the query point. KNN is an effective classifier to classify the small size sentence. The Euclidean distance equation is a main alternative to the similarity measure.∑√ (1)3.4. Performance Evaluation MetricsFinally the result is evaluated using the Accuracy, F-Measure, Precision and Recall. These four parameters are used to evaluate the performance of the classifiers.4. Results and DiscussionThe SuperFetch Reviews is considered as data set to test the performance of the present hybrid approach. The reviews are collected from the websites as well as from the various professionals. The present hybrid approach is tested on a SuperFetch data set in which three cases are considered to evaluate the results. All cases were carried out in Visual Studio 2010 are discussed in this section.Reviews are classified as positive and negative by the hybrid method. The effectiveness of the hybrid method is determined by the following parameters.∙Accuracy = (2) Where;TP is true positiveTN is true negativeFP is false positiveFN is false negative∙Precision = (3) ∙Recall = (4) ∙F-Measure = (5)Fig.2. Accuracy, Positivity and Negativity in case of 50 ReviewsThe Figure 2 shows the graphs which represent the accuracy, positivity and negativity in case of using 50 reviews. The positivity comes in the 50 reviews is much greater than the negativity.Fig.3. Precision, Recall and F-Measure in Case of 50 ReviewsThe figure 3 indicates the Precision, Recall and F-Measure in case of 50 reviews. The value of Recall is greater than the Precision and F-Measure.Fig.4. Accuracy, Positivity and Negativity in Case of 100 ReviewsFig.5. Precision, Recall and F-Measure in Case of 100 ReviewsThe figure 5 and 6 show that the result evaluation using 100 reviews. The results achieved using 100 reviews greater than using 50 reviews in Precision, Accuracy, F-Measure and Positivity. So result evaluation using 100 reviews quite effective than the result evaluation using 50 reviews.Fig.6. Accuracy, Positivity and Negativity in Case of 120 ReviewsFig.7. Precision, Recall and F-Measure in Case of 120 ReviewsThe figures 7 and 8 represent result evaluations using 120 reviews. The Precision, Recall and F-Measure in 120 reviews are at almost same level. The accuracy achieved is better than the previous two cases. So, the hybrid approach is more effective in this case mainly in terms of Accuracy.Table 1. Result Table for All CasesParameters 50 Reviews 100 Reviews 120 ReviewsPrecision 0.84 0.89 0.94Recall 0.97 0.96 0.96Accuracy F-Measure Positive% Negative% 84.310.9062.008.0087.130.9270.005.0090.740.9568.335.005. Conclusion and Future WorkPresent work concluded that the combination of K-Nearest Neighbor and Support Vector Machine produced better results on the basis of Accuracy, Precision, Recall and F-Measure. K-Nearest Neighbor improved the performance in the case of small reviews and Support Vector Machine improved the performance in case of large reviews are working as a single hybrid approach.There are two more parameters positivity and negativity are evaluated that shows most of the reviewers have positive thoughts regarding SuperFetch and the negativity percentage is very less, the remaining reviews are considered as neutral. So the results indicate that SuperFetch is a good feature in the memory management system. Future work includes the comparison of the present technique with existing techniques.AcknowledgementsI am grateful to my guide Assistant Professor Mrs. Naveen Kumari for all help and valuable suggestion provided by her during the study and special thanks to Associate Professor Mr. Michael Swift who help me in collection of reviews.References[1]X.
